IMPRCVEMENT IN STEAM-ENGINES.

Specification forming part of Letters Patent No. 124,801, dated March 19,1872.

Description of the Accompanying Drawing.

Figure 1 represents a side elevation of my invention complete,-drawn to a scale of one inch to the foot; Fig. .2, a plan View of the same, also on a scale of one inch to the foot.

Fig. 3 is a side elevation of the cylinder, drawn to a scale of three inches to the foot, the lower part being partly in section so as toshow the arrangement of the steam-passages, 850. Fig. 4 is a plan or top view of the same, drawn to the same scale. Fig. 5 is a front view of the frame and cylinder, on the same scale. Fig. 6 is a back view of the cylinder, showing the steam-chest below it, &c.

GenemZDcscm'ption. V A represents the frame. It is cast in one piece with the ribs B, and and D, thereby insuring great and sufficient strength without unnecessary weight. It is supported by the foot-pieces E, F, G, and H. J is the cylinder. It is bolted to the frame at K. L represents the steam-chest. It is placed on the lower part of the cylinder, and is cast in one piece with it, as shown in Figs. 1, 3, and 6. The arrangementof the valves is shown in the sectional part of Fig. 3, and is represented by the letter M. It is made in the form of a rolling valve, although any form of slide-valve may be used in its place; but I prefer the arrangement shown in the drawing. S S represents the inclined stea-m'passages, and R the exhaust-passage or port.

It will be readily seen that the arrangement of the valve below the cylinder and the steampassages S S, inclined as shown in said Fig. 3, affords a better and easier outlet for the con densed steam to escape or pass out the eX- haust-port.

The various parts common to a steam-engine are represented in the drawing as follows: '1 is the piston-rod; U, the connectin g-rod V, the crank; W, the fly-wheel;'X, the pump; Y, the eccentric; and Z, the cross-head, 85c.

Claim.

I claim as my invention- In a steam-engine constructed substantially as herein shown and described, I claim the combination of the steamchest L, inclined steam-passages S S, and the exhaust-passage R of the valve, said parts being constructed and arranged in respect to the cylinder J, and operating as set forth.
